What is OCN certification?

While RN licensure demonstrates the requisite entry-level knowledge to begin working in the field, it does not necessarily demonstrate to your employers or patients your dedication to continuing your education and broadening your knowledge and skills. The OCN certification process is voluntary and provides your employers and patients with the assurance that you are dedicated to obtaining and maintaining specialty knowledge in oncology nursing. OCN certification also provides comfort to your patients and rewards to you as an RN. Certification, while voluntary, may be necessary for advancement into higher level roles in your organization and can help open additional professional opportunities, including potential income increases.

OCN Study Guide Customer Success Stories

Our customers love the tutorial videos from Mometrix Academy that we have incorporated into our OCN test study guide. The OCN study guide reviews below are examples of customer experiences.

The book is so much easier to comprehend than the Core Curriculum offered by the licensing site. I need to be able to understand what I am reading without a lot of fluff, but also without just reading straight bullet points either. This book is the best of both worlds, easy to read and understand while being short and concise on the subject matter.

OCN Study Guide – Trent

I am really happy with this purchase. It is concise and user friendly. I love that is has 165 test questions which is the exact number of test questions that will be on the actual exam so I can practice taking the test timed and untimed. It also gives the rationales which is helpful to study. I am preparing to take the OCN exam in the fall of 2016 and am confident this product will help me succeed in passing the exam.

OCN Study Guide – Customer

The study guide format was perfect...all valuable information, no fluff or filler. Facts and information straight to the point. The "Test Taking Strategies" were extremely helpful, especially for someone like me who second guesses and over-analyzes questions too often. I even gained knowledge from the explanations of the correct answers for the practice test.

OCN Study Guide – Customer

I think that this book has been great so far- It breaks everything down and gives great rationales. Even though I’ve worked as an oncology nurse for years- some topics I’m just not as strong in since it’s not my field of focus... this does an amazing job of breaking things down and giving examples!

OCN Study Guide – Erica

I like how this book is in an easy to read format, without too much detail. I also like the tips on test taking and that there is a practice test included. I have just began to use this book but so far so good.

OCN Study Guide – Customer

OCN Secrets Study Guide is very helpful for studying and/or review. I heard about the product from an employee that recent took the OCN exam and successfully passed the exams. I am telling others about the study guide.

OCN Study Guide – Shelita

This book was the most helpful as I used several sources to study for this exam. I took the exam 3 times and passed by using this study guide prior to taken the exam the third time. I am using the book to help my daughter study for her OCN exam.

OCN Study Guide – Melisa

The formatting of the content sections of the study guide for the OCN makes studying for the exam easy and very effective. This study guide highlights the key areas to focus on for the OCN exam. Loved the Top 20 Test Taking Tips.

OCN Study Guide – Star

I have found this to be a very helpful tool in preparing for the OCN exam. The condensed review of topics and the clear explanation of test answers have been very helpful. Not overwhelming or filled with too much extra information.

OCN Study Guide – Eileen

I like how concise and organized the book is, especially how it matches the current OCN Test Content Outline. I took the test last year and I had a difficult time organizing the way I was studying. I'm really glad I bought this book.
